Final answer:

The surface area of a cube with a side length of 4 inches is calculated using the formula 6s². By substituting the side length into it, we find that the surface area is 96 square inches.

Step-by-step explanation:

The surface area of a cube with a side length of 4 inches can be calculated using the formula 6s², where 's' is the length of one side of the cube. Substituting 4 inches for 's' into the formula, we get:

  • Surface Area (SA) = 6 × (4 inches)²
  • SA = 6 × 16 square inches
  • SA = 96 square inches

Therefore, the surface area of the cube is 96 square inches, which corresponds to option B).
